Can I connect my Cable or xDSL modem to my PC running Linux?
Many Cable or xDSL providers have very little experience with Linux, and refuse to install the Cable or xDSL modem into a PC running Linux. You should investigate with the ISP and see if they allow Linux Installs, or if they are “Linux-Friendly”. You can find out more info on the newsgroups, or by checking out the Linux Cable Modem Section on http://www.CableModemInfo.
